COUPLING MEMBER FOR SCAFFOLDINGS

摘要

A coupling member includes a hook-shaped coupling part arranged to be hooked into a gripping part of an upright and a locking arrangement switchable between a locking position and a release position. Further, the locking arrangement includes a pivotally attached first clamping part and a wedge-shaped locking part, which is slidable between a locking position and a release position. The wedge-shaped locking part is arranged to push the first clamping part towards the upright and the gripping part by means of wedge action. Moreover, the first clamping part comprises two transversally spaced apart side parts which jointly define a cavity there between. The first clamping part is arranged externally on the hook-shaped coupling part, and is arranged partly within the cavity. Further, each of the side parts includes fastening means for pivotal attachment of the first clamping part to the hook-shaped coupling part.

1. Coupling member for coupling scaffolding elements to uprights in a scaffold or the like, said coupling member having a longitudinal direction and a transversal direction, said coupling member comprising:
a hook-shaped coupling part arranged to be hooked into a gripping part of said upright; and a locking arrangement switchable between a locking position, in which said coupling member may be secured to said upright and, and a release position, in which said coupling member may be released from said upright, wherein said locking arrangement comprising: a first clamping part that is pivotally attached to said hook-shaped coupling part about a pivoting axis, and arranged to, in said locking position, interact with at least one of said upright and said gripping part for tightening the coupling between said coupling member and said upright; and a wedge-shaped locking part which is slidable between a locking position and a release position, said wedge-shaped locking part being arranged to, during motion from said release position to said locking position, by means of wedge action push said first clamping part towards said upright and said gripping part for interaction with at least one thereof, and wherein said first clamping part comprises two transversally spaced apart side parts which jointly define a cavity therebetween; said first clamping part is arranged externally on said hook-shaped coupling part, such that said hook-shaped coupling part is arranged at least partly within said cavity; and each of said two side parts comprises fastening means for said pivotal attachment of said first clamping part to said hook-shaped coupling part.
